Although the motor functions of the arm are not overly complex, the use of the piezoelectric effect in the arm, and the processor are not yet in existence. Unlike many inventions, the Piezo-Sensory arm's development will depend on several technological advances.

In order to develop the Piezo-Sensory arm, scientists first need better understanding of the nervous system. The arm depends on the processor to be able to understand the pulses of the nervous system. By doing extensive research of the nervous system, scientists can understand these pulses and decipher the different kinds of pulses and what they want the body to do. This cannot only lead to the development of superior prosthetics, but also greater medical technology in other fields.

In the Piezo-Sensory arm, the crystals will be under a lot of strain. Every movement of
the arm will slowly deteriorate the crystals, therefore the damage or snapping of the
crystals can be quick and is inevitable. However, we can significantly increase the crystals
durability by integrating it with different materials, but to do this, we need greater
knowledge about materials engineering for piezoelectric crystals. The fact that this is also
a solid-state system will also ensure that the piezoelectric crystals will have a very long life
span and probably out last all other systems of the arm.

In order for the Piezo-Sensory arm to be developed efficiently, we need better miniaturization of electronics. Our current technology on electronic miniaturization is enough to develop the arm, however it would not be too efficient. With better miniaturization of electronics we can make the equipment more efficient, and therefore also lowering the prices of the arm. If the miniaturization of electronics progresses quickly, scientists may even be able to add more feedback from the arm.
